Question

От норки одновременно в противоположных направлениях побежали 2 ёжика со скоростью 2 м/с и 3 м/с. какое расстояния будет между ежиками через 15секунд

Answer 1

2 *15= 30м
3*15= 45 м
30+45 = 75 м

Answer 2

Calculation of the Distance Between Hedgehogs

To calculate the distance between the two hedgehogs after 15 seconds, we need to determine the distance each hedgehog travels in that time period.

Given: - Hedgehog 1 runs with a speed of 2 m/s. - Hedgehog 2 runs with a speed of 3 m/s.

We can calculate the distance each hedgehog travels using the formula:

Distance = Speed × Time

For Hedgehog 1: Distance1 = 2 m/s × 15 s = 30 m

For Hedgehog 2: Distance2 = 3 m/s × 15 s = 45 m

Therefore, after 15 seconds, Hedgehog 1 will be 30 meters away from the starting point, and Hedgehog 2 will be 45 meters away from the starting point.

To find the distance between the two hedgehogs, we subtract the initial distance of Hedgehog 1 from the initial distance of Hedgehog 2:

Distance between the hedgehogs = Distance2 - Distance1 = 45 m - 30 m = 15 m

Therefore, the distance between the two hedgehogs after 15 seconds will be 15 meters.
